RegeneRx Common Stock to be Quoted on OTC Bulletin Board

ROCKVILLE, Md.--(BUSINESS WIRE)-- RegeneRx Biopharmaceuticals, Inc. (“the Company” or “RegeneRx”) announced today that beginning with the opening of trading on December 23, 2010, the Company’s common stock is expected to be quoted on the OTC Bulletin Board under the symbol RGRX following its suspension from the NYSE Amex as of that date.

As previously announced, on October 26, 2010 the Company received notice from the staff of the NYSE Amex that the Company had failed to regain compliance with continued listing standards and, accordingly, the Company’s securities were subject to delisting proceedings. The Company appealed the determination and initially requested a hearing before a Listing Qualifications Panel. However, the Company withdrew the request on December 15, 2010.

“While we are disappointed that we were unable to maintain our NYSE Amex listing, we continue to focus on our dual missions of generating positive clinical data and seeking strategic partners to develop our product candidates,” stated J.J. Finkelstein, RegeneRx’s president and chief executive officer. “We will pursue our ongoing clinical and business initiatives while our common stock is quoted on the OTC Bulletin Board and may seek to return to the NYSE Amex or NASDAQ at a time when we can readily meet the initial and continued listing requirements.”

While its common stock is quoted on the OTC Bulletin Board, the Company plans to file periodic reports with the SEC pursuant to the requirements of the Securities Exchange Act of 1934, as amended.

About RegeneRx Biopharmaceuticals, Inc.

RegeneRx is focused on the development of a novel therapeutic peptide, Thymosin beta 4, or Tβ4, for tissue and organ protection, repair and regeneration. RegeneRx currently has three drug candidates in clinical development and has an extensive worldwide patent portfolio covering its products.

RGN-352 is an injectable formulation to treat cardiovascular and central nervous system diseases, as well as other medical indications. RegeneRx is initially targeting RGN-352 for the treatment of patients who have suffered an acute myocardial infarction, or heart attack. Recent pre-clinical efficacy data suggests that RGN-352 may also benefit patients with multiple sclerosis, stroke and traumatic brain injury. RegeneRx recently received a $3 million, three-year development grant from the NIH to support the company’s acute myocardial infarction program. RGN-259 is a sterile, preservative-free topical eye drop for ophthalmic indications. RGN-137, a topical gel formulation, is currently being evaluated by RegeneRx in a Phase 2 clinical trial for the treatment of the orphan skin disease epidermolysis bullosa. Other potential uses for RGN-137 include the treatment of chronic dermal wounds and reduction of scar tissue.

In addition to the pharmaceutical product candidates described above, RegeneRx is pursuing the commercial development of peptide fragments of Tβ4 for potential cosmeceutical use. RegeneRx holds numerous patents and patent applications worldwide related to its products and holds an exclusive worldwide license from the National Institutes of Health, as well as other licenses related to Tβ4.
